The packaging bag comprises a front surface and a back surface, wherein the bottom of the front surface and the bottom of the back surface are jointed together through glue, ultrasonic welding or heat-seal. After the bottoms are jointed together, the bottoms are folded back to tightly attach to the front surface or the back surface. The bottoms are glued with the front surface or the back surface through a mucilage glue layer, or outer side faces of the bottoms are glued with the front surface or the back surface through the mucilage glue layer. The packaging bag has the advantages of being attractive in appearance and convenient to process, and not leaking dust or other particulate matter.
Description
Technical field
The utility model relates to a kind of packaging bag.
Background technology
The packaging bag of current packaging bag, particularly plastic woven material, bottom directly are stitchings or bonding, leak particulate matters such as powder easily, and profile is not attractive in appearance yet, and stacking is irregular.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of later-model packaging bag.
To achieve these goals; The technical scheme that the utility model is taked is: a kind of packaging bag; Comprise front surface and surface, back; The on front surface and back surface fits together through gluing, ultrasonic welding or heat-sealing, and front surface or surface, back are close to folded in the back of fitting, bottom, and between bottom and front surface or the surface, back or the lateral surface of bottom and front surface or back be surperficial, and to pass through adhesive-layer bonding.
To the sack folded inside, after folding, fit with its inside face respectively in two sides and front surface or surface, back along separation point for the two sides that also comprise bag, two sides and front surface or surface, back.
The beneficial effect of the utility model: good looking appearance, easy to process, can not leak particulate matters such as dust.
Description of drawings
The lateral plan that packing material is arranged in Fig. 1, the utility model;
The front view of Fig. 2, the utility model.
The specific embodiment
A kind of packaging bag; Comprise front surface 1 and surface, back 2; 21 places, bottom on front surface 1 and surface, back 2 fit together through gluing, ultrasonic welding or heat-sealing; Front surface 1 or surface, back 2 are close to folded in the back of fitting, bottom 21, and it is bonding that adhesive-layer 3 is passed through between bottom 21 and front surface 1 or the surface, the back 2 or lateral surface of bottom 21 and front surface 1 or back surperficial 2.Fold back after the sack place on front surface 1 or surface, back 2 is bonding (" back " here is the other direction of relative sack); Again adhesive-layer 3 is bonded in front surface 1 or surface, back 2 with the sack after bonding (also claiming bottom 21) after folding.Adhesive-layer 3 generally is to be similar to pressure sensitive adhesive double coated viscose glue.Sack place after bonding has like this also been covered by adhesive-layer 3.The two sides that also comprise bag, two sides and front surface 1 or back surface 2 along separation point to the sack folded inside, folding after, fit with its inside face respectively in two sides and front surface 1 or surface, back 2.Profile is also attractive in appearance, and processing is also convenient, simultaneously, also can not leak particulate matter, and stacking is neat.
